Title: Marine craft variable pitch propeller - has mechanism which can set different blades at different pitch angles
Inventor: GRZANNA KURT
IPC: B63H3/00
Filed: 1989-07-26
Abstract: The variable pitch propeller for a marine craft has each blade (10,11) mounted in a bearing in the propeller hub (12) so that the blade can rotate about a radial axis.

Title: Fixing process temp. control for electrophotographic reprodn. - has master control unit and fixed frequency pulse generator enable temp. sensor output to be tracked
Inventor: SHIOKAWA MASAMI
IPC: H05B3/00
Filed: 1989-12-28
Abstract: The apparatus consists of a fixing unit (1) and an halogen heating lamp (2) which is switched on and off by a relay (SSR) within a control unit (3). The control unit (3) is in turn regulated by a master controller (CPU4) which receives information from a temperature sensor (5) at fixed intervals.  An external timing unit (6) provides a trigger pulse to the master controller (CPU4) at a fixed frequency, e.g. 100HZ and this determines the interval between successive temperature measurements. The master control (CPU4) examines incoming temperature data for conformity with a preset temperature range and for trend (rising or falling). It is thus able to anticipate the rate of approach to the upper and lower limits of the range and generates a coded signal to the relay control unit (3), in a digital form after a commensurate delay based on trend. By this means circuit switching is minimised and spurious short duration disturbances in the temperature sensing circuit are ignored. USE/ADVANTAGE - Reduced number of occasions when lamp is switched to maintain temperature with increase life of lamp. Master control unit logic permits delayed response to temperature change by noting trend as well as instantaneous value. Spurious circuit disturbances are thereby suppressed and malfunction of system reduced.

Title: Weight-monitored evapn. of heated liq. - using gas delivered by nozzle rapidly retracted on reaching desired vol.
Inventor: GORMAND PHILIPPE
IPC: B01L7/00
Filed: 1990-12-28
Abstract: Liq. to be automatically reduced by evapn. to a specific vol., measured by wt., is held in an open-topped container (8) fitting into the cavity of a surrounding heater (1), and resting on an internal or external load cell (2). Evapn. is caused by a stream of inert gas delivered from a mobile nozzle (4) and impinging on the liq. sample surface (a). When processed signals from the load cell indicate the target wt. has been reached, the container is automatically lifted out of the enclosing heater, and a valve (7c) promptly cuts off the supply of vaporising gas, to ensure evapn. stops quickly.  The container, where a temp. of 20-150 deg.C is maintained, has no direct contact with the surrounding heater. USE/ADVANTAGE - Prepares analysis samples from repeated large amts. of contaminated liq., by evapn. in standard reproducible conditions, with the process readily automated.

Title: Adaptive automatic setting of motor vehicle transmission - correcting for torque lost to ancillary circuits
Inventor: ASADA MICHIO
IPC: F16H59/50
Filed: 1991-06-28
Abstract: The transmission control monitors the torque output from the engine as well as the state of any ancillary circuits driven from the engine, e.g. air conditioning unit. If the ancillary units draw torque, the mode of control for the automatic transmission is correspondingly adjusted by the control, i.e. it takes account of the drop in available torque. The adaptive control modulates the control signals by a programmed amount and operates the drive ratio accordingly to maintain the vehicle drive. The programmed control is a simple electronic control with relatively simple correction. ADVANTAGE - Improved torque control, less risk of engine stalling.
